` EXPLOSIVE SHELL.

,To all whom 'it may concern: y.

Be 1t known that I, JOSEPH KRUPKA, 4subiject of the Emperor of Austria, residingat Coalridge, in-tlie county of Xoble and State Vof Ohio, have invented 'certain new and useful Improvements in Explosive Shells, of which the followingjis a specification.

This invention relates to certain new and yuseful improvements in explosive shells.-

The lprimary object of the invention is the pro-vision of an explosive shell that is easy and inexpensive to manufacture and isl adapted to explode upon violently striking any object during the forward movement thereof.

A further object of the device is toprovide an explosive shell having` an internal eX- ploding mechanism arranged with'a firing means retained inoperative during the handling and shipment thereof but adapted for operative positioning whenired from a gun or projector.

lith these general objects -in view and `others that. will-appear as the nature of the invention is better understood, the same consists in the' novel construction, combination 'and arrangement of parts hereinafter fully Vdescribed, illustrated in the accompanying drawing and pointed out4 in the appended. claims.

In the drawing forming a part. of this application and in which like numerals refer to corresponding parts throughout the several views;

Figure 1 is a central longitudinal sectional view through the device with the parts thereof inoperatively positioned. Fig. 2 is a similar view with the mechanism operatively7 arranged but with the eX- plosive removed.

Fig. 3 is a view similar to Fig. 1 with the mechanism-illustrated in its exploding position.

Fig. 4 is a transverse lsectional View taken upon line IV-IV of Fig. 1..

Fig. 5 is a transverse sectional view taken upon line V--V of Fig. 3, and,

Fig. 6 is a forward portion of a modied form of torpedo shown in central longitudinali section.

The present invention broadly consists in a shell 10 adapted to receive an explosive such as dynamite 1-1 and having a bullet or point 12 arranged in the forward open end of the shell while suitable mechanism is pro Specification'of Letters Patent.

the bullet.12 strikes an object. A tubular..

casin'g or-well 13 is centrally held within the shell 10 surrounded by the dynamite 11 by means of oppositely,projectingarms 14 attached to lugs 15 upon the inner wall oi' the shell, an opening 16y being provide-d in the bottom of the, well 13 adapted to receive a suitable percussion cap or fulminate.

A'piston 18 is slidably arranged within the well 13 having an inner 'head 19 in the form of a disk .slidably fitted within the well and provided with .a centrally projecting point or liring pin 20 adapted for exploding the cap17 when the-piston is moved in. wardly through the opening 16. The outer head 21 of the piston is also in the form of a disk and has a Vcentrally projecting rod 22 carried thereby sl'idably arranged centrally through the bullet 12 within anaxial bore 23 provided in the bullet.l A j A- lever 24 is hinged as at 25 within the shell 10 adapted to bear. upon the port-ion. 26 of the piston 18- andl having an'operating bar 26 slidably -carried through a side strap 28 upon' the well 13 and within'an opening portation, the rod 221is positioned slightlyv inwardlyl of the outer end ofthe bore 23 with the piston head 21 lying flush within the Well 13V while the lever 24 will be sub-4 stantially parallel with the arms 14 and the lower end' of the bar 27 will be slightly inwardly of the outer face of the base 29.

This arrangementof the rod 22 will permitV the positioning ofthe suitable sealing orI retainingmeans such as wax 30 in the outer end of the bore 23`,and a similar quantitV of wax 31' within the outer end of the opening 28 as best illustrated in Fig. l'of the drawing. The torpedo is adapted' to be fired .or projected by a suitable member such outwardly of the bore 23as illustratedin Fig. 2 and-whereupon when the free end of the rod 22 and the bullet 12 strike an object, the'rod 22,will be forced inwardly for mounting the piston 18v in a corresponding direction, thereby forcing thepin 2O through the'cap 17 and lexploding the same.

`for igniting the explosiveI 11 which is adapted 'to disrupt-the shell 10, separate the bulfi let 12A therefrom and project any such articles as sora-piron 32 which is positioned.-

Within thel shellA inl all directions.' A. serviceable torpedo for. times ovvar isarranged'. which' may be made of any desired size, it being `nl iderstood that the bar- 27 may be moved inwardly forprojeoting the rod 22 in -any desired mannerv such as by -meanszof a 'fpin (not shown),`l arranged in ".thegun by means` of which the torpedo'is projected. It Will be understood- `that the explosive 11 is arranged to permit ofeelight movement in the rod 22, lever'24l and bar 27.

'I j Without 4discharging); the device.

. in Fig. 6 'the shell'10lis arranged with a; bullet 12 having a' rod vcentrally and slidably arranged therethrough, and procomes in contact With the object'during the Inthe modified form of .the device shown vided With a head 21- With a Well 13'.. Dynamite .112 is provided in the shell 10 While a percussion cap 17 .is arranged. adjacent the bottom of the Well 13"for` engagement by the head 21 when the bullet osaid rod forward movementofthe torpedo. The exploding ofthe cap 17 is adapted to burst the Well I13 for igniting. and discharging the dynamite 11'.'
